### Description

At very small fractional momentum of the nucleon, the increase of the gluon density is expected to saturate, but no experimental measurements have yet shown this saturation effect without ambiguity. Measurements of prompt photon production at forward rapidity in p-Pb collisions represent suitable tests for the onset of the gluon saturation.
The LHCb experiment is well suited for prompt photon measurement as it is equipped with tracking, particle identification and calorimetry detectors that cover the same pseudo-rapidity acceptance 2 < eta < 5. New results on prompt photon measurements in p-Pb collisions at $\sqrt{s_{NN}}=5$TeV will be presented.
